The Juan Fernández fur seal (Arctocephalus philippii) is the second smallest of the fur seals, second only to the Galápagos fur seal. They are found only on the Pacific Coast of South America, more specifically on the Juan Fernández Islands and the Desventuradas Islands. There is still much that is unknown about this species.
Arctocephalus forsteri (common names include the Australasian fur seal, [3] South Australian fur seal, [4] New Zealand fur seal, [5] Antipodean fur seal, or long-nosed fur seal) is a species of fur seal found mainly around southern Australia and New Zealand. [1]
Nonetheless, all fur seals have certain features in common: the fur, generally smaller sizes, farther and longer foraging trips, smaller and more abundant prey items, and greater sexual dimorphism. For these reasons, the distinction remains useful. Fur seals comprise two genera: Callorhinus, and Arctocephalus.

Adult Guadalupe fur seals are dark brown or dusty gray with yellowish silver manes, called guard hairs, on the back of the neck. [3] Guadalupe fur seals are sexually dimorphic in size, as males are much larger and heavier than females; males can grow to about seven feet in length and weigh upwards of 400 pounds, while females are typically only five feet long and weigh about 110 pounds.

The subantarctic fur seal (Arctocephalus tropicalis) is a species of arctocephaline found in the southern parts of the Indian, Pacific, and Atlantic Oceans. [3] It was first described by Gray in 1872 from a specimen recovered in northern Australia—hence the inappropriate specific name tropicalis .
The fur seals’ habitat is naturally restricted which makes them more threatened by environmental changes. Other potential and existing threats are tourism, oil spills, and boat collisions. Oil spills would be particularly damaging to the fur seal as their thick pelage is an important part of their thermoregulation.
The Antarctic fur seal (Arctocephalus gazella) is one of eight seals in the genus Arctocephalus, and one of nine fur seals in the subfamily Arctocephalinae.Despite what its name suggests, the Antarctic fur seal is mostly distributed in Subantarctic islands [3] and its scientific name is thought to have come from the German vessel SMS Gazelle, which was the first to collect specimens of this ...
